INTAKE FOR GAS-ENGINES..

Specification of Letters Patent.

Patented June 2, 1914i,

Application filed .Tune 13, 1913. Serial No. 77E-,431.

7 10 all zii/mmmuy/ eminem Be it known that l', ll/fonron E. HIDDEN, a citizen of the United States, and resident of East Grange, county of Essen, and State of New Jersey, have invented certain new and useful Improvements. in intakes for Gas-Engines, of which the following is a specification.

This invention relates to an improved arl or manifold in which the several cylinders are connected together successively in the. order of their firing.

lln the draai/ings like parts in the s. eral viewshave heen given the same reference numerals.

Figure l is a representation of the ordinary arrangement of the intake upon a four cylinder engine. Fig. 2 is a side elevation illustrating one arrangement of my imH proved form of intalre for a four cylinder engine. llfig, 3 is a, plan vieuv of ltig. 2.

ln Figs. 2 and 8, the cylinders of the en: gine are numbered l, 2, 3 and l respectively Vin the order of their tiring. The carburetor connected with the lower end of the intalre at t, from which the gus In'iinture passes through the intalre pipes in the direction indicated hy the arrows.

The explosive ehurge is drown into the cylinder l through the pipes l and 7 and as its intake valve eloses the Cylinder Q nent draws in its .Cfuppljyu eontiniling the llow of the gas through the pipes 8 and 9. The eyliiiiler nent draws-in its supply of gas through its intalre l0, still Continuing the llow through the pipes 6 and 8 and also drawing an additional supply directly from the earhureter through the pipe ll. fis the intake valve closes in the eyliiuler d the cylinder l draws in its supplyA of gas through its intake pipe 'li-l, continuing the llow from the pipes 8 and' ll through the pipe 12, and as 'its intake valve closes the lieu' of gas continues through the pipe i2 `eomhinatifni with a to the point where it joins the pipe 6 and the intake pipe 7 for the cylinder l, where the cycle of operation is repeated. lt Will thus he seen that. the gas supply is .continuous and Hows successively toeach cylinder" 6o as the same draws in its supply. llhis op eration is distinguished from the ordinary arrangement shown in Fig. l, in which the gas flows to the cylinders l and il through the pipe le but is then stopped. in its flow o5 while the cylinders 3 and are drawing in their supply through the pipe 15. rfhe sue tion from the cylinders 3 and et also tends to draw some of the mixture from the pipe ll in a reverseA direction, with the result '.10 that u lien the intake valves of the cylinders i and 2 again open the mixture which is first drawn in from the pipe ld is weaker or more rareed than the proper mixture until the pipe 14 has been emptied of this 75 I lilith the improved arrangement, as illustinted in Figs. 2 and 3, it Will be seen that the mixture Will be uniform, as the floW is continuous and in one direction through the several pipes, resulting in a perfect mixture heilig supplied to the cylinders and, eonsei quently, u much smoother operation of the engine and an increase in .power from the explosions:

lt will be understood that the arrangement as shown is merely illustrative for .one paro ticular type of engine. In engines having i. a dillereut ordernaf firing for the cylinders it is only necessary to change the point of` supply so as to preserve the continuous flow of gas successively to the cylinders in. the order of their firing.

What l claim is:

l. ln an explosive engine, the combination with a plu ality of cylinders and a source of fuel supply, of a plurality of intake pipes arranged in series and connecting successively each of the cylinders in the order of their tiring to provide a continuous dow of in the same direction therethrough to iid eylinders.

Q. ln a four Cylinder explosive engine., the plurality of cylinders and a earlmreter, ot intake. pipes extending from the. carburetor to the iirst and third cylinders in the order of their tiring, arjon- 1M) necting pipe from the first to the Second and third cylinders, and a connecting pipe from the third to the fourth. and first cylinders, said pipes being interconnected at the first and third cylinders.

3. In an explosive engine, the combination with a plurality oi cylinders and a carbureter, of a series of intake pipes connectving successively each of the cylinders in the order of their firing, said pipes being interconnected at alternate cylinders, "and supply pipes from the carbureter to said intake pipes.- v

4. In an explosive engine, the combination with a plurality of cylinders and a carbureter, of a series of intake pipes connecting successively each of the cylinders in the order of their firing, said pipes being interconnected at alternate cylinders, and suptothe third, fourth and iii-st cylinder sncf* cessively, said intakes being); joined atthe first and third cylinders.-
